According to Guangming.com, in July this year, the Beijing police found that the alleged offender Zhang transferred more than 20 million yuan of stolen money through overseas underground banks, causing private enterprises to suffer serious losses. Through the analysis of suspicious transactions, the police gradually locked Lu and more than a dozen accounts associated with him. After work, they transferred a large amount of unknown funds overseas in more than three years, and the amount involved was as high as 800 million. After investigation, the police found that the criminal gangs led by Lyu provided funding channels for telecommunications fraud, online gambling and other crimes. The upstream criminal gangs often used domestic RMB funds to buy virtual currencies from coin speculators and coin merchants through Lyu and others, and then sold virtual currencies to overseas sellers through virtual currency platforms outside the border to obtain foreign exchange, so as to achieve the purpose of transferring illegal domestic income overseas.
